Bio12 CellTrasnsport

SLS Bio 12 Cell Transport HO

Active trasnport Transport against a concentration gradient that requires chemical energy
Carrier Protein involved in the movement of ions, small molecules, or macromolecule, across a biological membrane
Cell Membrane the semipermeable membrane surrounding the cytoplasm of a cell.
channel protein A protein that allows the transport of specific substances across a cell membrane
concentration gradient from higher concentration to lower concentration
diffusion the net movement of molecules or atoms from a region of high concentration to a region of low concentration
endocytosis a form of active transport in which a cell transports molecules into the cell by engulfing them in an energy-using process.
exocytosis a form of active transport in which a cell transports molecules out of the cell by expelling them in an energy-using process
facilitated transport A form of passive transport in which materials are moved across the plasma membrane by a transport protein down their concentration gradient
fluid mosaic membrane model In this model, a flexible layer made of lipid molecules is interspersed with large protein molecules that act as channels through which other molecules enter and leave the cell.
glycolipid lipids with a carbohydrate attached. Their role is to provide energy and also serve as markers for cellular recognition.
glycoprotein any of a class of proteins that have carbohydrate groups attached to the polypeptide chain. Also called glycopeptide.
hydrophilic having a tendency to mix with, dissolve in, or be wetted by water.
hydrophobic tending to repel or fail to mix with water.
hypertonic a solution of higher osmotic pressure than another solution with which it is compared
hypotonic any solution with a lower osmotic pressure than another solution
isotonic a solution having the same osmotic pressure as some other solution
osmosis a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one
passive transport processes The movement of particles or ions across a semipermeable membrane without the expenditure of energy.
phagocytosis the engulfing of larger, solid particles
phospholipid a lipid containing a phosphate group in its molecule
phospholipid bilayer a two-layered arrangement of phosphate and lipid molecules that form a cell membrane
pinocytosis the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.
pressure gradient from higher pressure to lower pressure
selectively permeable a membrane that allows certain molecules or ions to pass through it by means of active or passive transport.
tonicity a measure of the amount of substance dissolved in a liquid
